Nantlle Ridge Hiking Guide

The perfect ridge walk

Published By: Daniel Woodley. Updated: 22nd April 2024. Filed at: Hiking Routes. Disclosure: I may earn a commission from purchases made via links.

Nantlle Ridge is one of the finest ridge walks in the UK. At just over 9km long and far quieter than the nearby Snowdon range, this ridge is well worth a visit.

Expect stunning views, exposed ridges and easy scrambling sections.

Here I’ll outline the route from Rhyd Ddu, finishing at Garnedd Goch, just above the village of Nebo. I did this route in 2023 and then returned the same way for a double traverse – that was a very long day for me (18km) and I had some very sore legs at the end.

Parking For Nantlle Ridge

Where to park will depend on whether you plan on hiking this route one way or returning to the start point.

On my first traverse of Nantlle Ridge, I parked at Rhyd Ddu train station (park here or here ) and did a double traverse, there and back – it was a long day and one of the harder hikes I’ve done in Snowdonia.

For my second visit, I did a one-way route so I parked a car in the village of Nebo ( ) and drove to Rhyd Ddu and parked the second car at the train station for the start.

I’ve seen many hikers park at one end and only traverse half of the ridge as the full there-and-back is 18km of hard strenuous hiking.

Rhyd Ddu to Y Garn

From the station car park, I went over the road and headed west on the well-made path and then onto the rugged east ridge of Y Garn.

This section of the route is quite a slog with a mixture of grass and gravel/stones underfoot.

There’s no scrambling on this first section and the summit is 633m above sea level.

Y Garn to Mynydd Drws-y-Coed

From the summit of Y Garn, I took the obvious path south for 1km to the summit of Mynydd Drws-y-Coed.

The west side of this exciting ridge is steep and offers delightful views down the valley.

There is some very light and short-lived scrambling over jumbled rocks in this section, but the difficulty never goes above grade 1.

Mynydd-Drws-y-Coed to Trum y Ddysgl

From Mynydd Drws-y-Coed, the path descends and veers to the right (west) before it rises to the second-highest summit on the Nantlle Ridge – Trum y Ddysgl.

This path to this summit is slightly steeper but is mostly dirt, well-trodden and easy to follow.

Trum y Ddysgl to Mynydd Tal y Mignedd

The section of the Nantlle Ridge starts on the summit of Trum y Ddysgl and takes the hiker southwest on a well-trodden path to The Obelisk on the summit of Mynydd Tal y Mignedd.

As you can see from the footage, the path is clearly visible and easy to follow.

From the Obelisk to Craig Cwm Silyn

I’ve met a few hikers that only went as far as the Obelisk and then turned back but I’ll show you the rest of the route.

From the Obelisk, head south on a grassy ridge for 400m and then down a steepening path to the double col of Bwlch Dros Bern. From here, the route up to Craig Cwm Silyn beckons; take the route just to the right of the ridge crest if you enjoy scrambling (grade 1) or further right to avoid much of the scrambling.

Stay true to the crest (scrambling) or follow the path slightly to the right to avoid the steep sections

Craig Cwm Silyn to Garnedd Goch

From Craig Cwm Silyn, follow the broad featureless grassy ridge to the final summit of Garnedd Goch.

Note: I didn’t have any issue with navigating this section but I could imagine in low cloud/visibility, a map and compass would be required, this section of the route is truly featureless.

From this end point, you can either reverse the route for a mammoth 18km double traverse or head south-west towards the village of Nebo if you dropped off a car earlier in the day.

My Thoughts on Nantlle Ridge

I’ve done Nantlle Ridge twice and really enjoyed it both times.

The views on this quieter side of Snowdonia are stunning, and getting away from the crowds is always a bonus.

I found the double traverse (there and back) quite difficult as it was a hot day and 18km of mountainous trekking left me with very sore legs!

As a hiking route, I rate Nantlle Ridge very highly, but there’s very little scrambling en route, and most of it is very easy or can be avoided entirely.


This route is best avoided on really windy days as the ridge is exposed.

There are only a few places to fill up water bottles, so if you usually filter stream water en route, you’ll need to bring plenty with you.

Parking is limited in Rhyd Ddu and in Nebo, especially on busy summer weekends.

Regular mountain footwear will be just fine on the Nantlle Ridge. I’ve worn La Sportiva TX4 and also La Sportiva Trango Tech boots up there without issue.
